Formula One cars are equipped with a data logger which records exactly how you use the controls available to you, such as Steering, Throttle and Brake, and how the car reacts to your inputs and performs from an engineering perspective. This logged data is referred to as Telemetry.
F1 Challenge 99-02 Telemetry is an extremely powerful utility designed primarily for advanced drivers who are familiar with the advanced vehicle setup pages and the concept of data logging/Telemetry as described above.
By studying telemetry and comparing different laps, you will be able to determine where you are gaining and losing time on any given lap and why. This should enable you to improve your driving style and develop vehicle setups specifically to suit the way you drive, ultimately enabling you to produce faster lap times.
To view your telemetry, drive a few laps, then enter the Vehicle Setup page and click the Telemetry icon. The F1 Challenge 99-02 Telemetry utility will load and import your telemetry ready for you to begin analysing it.
At the top left of the F1 Challenge 99-02 Telemetry display, you will see the following four icons:
Load Lap
Click this icon to open a popup selection box that allows you to load or delete any laps you may have saved.
Click this icon to launch Wordpad and display this help file.
Click this icon to open an information box displaying the version number and other miscellaneous information about the F1 Chall 646h75g enge 99-02 Telemetry utility.
Lap Listing Area
The name of the country for the circuit you have loaded is displayed and underneath this a number of rows, comprising a number, name and lap times. The number of rows varies depending on what telemetry and laps you have loaded)
The first row in this area, colour coded grey and prefixed with an asterisk (*), is reserved for the current reference lap loaded, whilst all other rows display any telemetry and laps you may have loaded.
Note that when your telemetry is imported, the current reference lap is also imported and it's telemetry displayed, colour coded grey. In addition to this, your fastest lap from the telemetry imported is colour coded and displayed accordingly in the colour assigned. Your laps are always colour coded in such a way that they are easy to compare against the grey reference lap.
Position the cursor over any lap and click the Left Mouse Button (LMB) to toggle the display of that lap's telemetry on and off.
Move the cursor over any lap time to access the following options:
Assign Colour
Click on any of the brightly coloured squares to assign that colour coding to a lap.
Statistics
Click this icon (upper left of panel) to popup a box displaying various statistics about the selected lap.
Click this icon (upper right of panel) to save the current lap to your hard drive in order to refer back to it in the future Note: Imported telemetry is not stored permanently on your hard drive.
Check Lap
Click this icon (lower left of panel) to check the selected lap for corner cutting and general validity.
Set As Reference Lap
Click this icon (lower right of panel) to overwrite the current reference lap and store the selected lap as the reference lap.
Telemetry View
Different windows are displayed in the main area depending on the aspect of telemetry you elect to view. Click the left/right arrows or drop down list icon to change the Telemetry View. The default view is the 'CHASSIS OVERVIEW'.
CHASSIS OVERVIEW
Displaying windows for track position, velocity, longitudinal/lateral G and RPM this view is ideal for general analysis of any telemetry.
Velocity (Speed) is measured in MPH.
On the G force chart, you'll notice that during braking, weight comes forward (up). Whilst all drivers will brake initially in a straight line, the best drivers come off the brake gradually whilst turning in to the apex - a technique known as trail braking. On this chart you will see that a driver who does not trail brake or push the car to it's limit does not effectively exploit the limits of grip which lie towards the edges of this window - i.e. Your data should be spread out away both axes. The image below shows a reference lap (in grey) with a good trail braking technique compared to that of a lap (green) that is inferior in this regard.
INCREMENTAL TIME DIFFERENCE
Displaying windows for track position, time difference, and velocity, this view is ideal for analysing the amount of time lost or gained over any given part of the track.
ENGINE AND GEARBOX INFORMATION
Displaying windows for track position, velocity, engine RPM, gear and rear wheel speed differential. This view is ideal for analysing engine stress and differential lock.
TRACK VIEW
Displaying a single window for track position this view is ideal for analysing driving lines and track position.
TRACK AND VELOCITY TRACE
Displaying windows for track position and velocity, this view is ideal for analysing velocity with regards to both straight line and cornering speed.
DRIVER INPUTS
Displaying windows for track position, velocity, throttle, brake, steering, gear and clutch. This view is ideal for analysing driving style and technique.
WEATHER
Displaying windows for track position, air temperature, track temperature, rain and track dampness. Use this view to analyse the effects of weather.
Temperatures are measured in degrees Centigrade whilst rain and dampness are rated from 0-100%. 0% being dry.
In addition to the standard Telemetry views, advanced views, are also available as follows:
DAMPER VELOCITIES
Displaying windows for raw damper velocities at each wheel, track position and velocity. This view and DAMPER VELOCITIES (SMOOTHED), below, is ideal for analysing the way in which your dampers are reacting.
On the damper velocity charts, when the trace is positive the damper is rebounding (ride height is increasing), when negative, the damper is compressing (ride height decreasing).
DAMPER VELOCITIES (SMOOTHED)
Displays windows for smoothed damper velocity at each wheel, track position and velocity.
The smoothing process helps to isolate the high frequency damper movement (eg. bumps) from the low frequency movement (eg. ride height change through heavy braking).
FRICTION CIRCLE
Displaying windows for track position, velocity and longitudinal/lateral G. Use this view to analyse your consistency tyres' grip limits.
CHASSIS ACCELERATIONS XYZ
Displaying windows for track position, velocity, longitudinal (X), lateral (Y) and vertical (Z) acceleration and velocity, this view is ideal for analysing chassis acceleration in all directions.
FRONT AND REAR RIDE HEIGHT
Displaying windows for track position, velocity, front ride height and rear ride height. This view and FRONT AND REAR RIDE HEIGHT (SMOOTHED), below, is ideal for analysing your ride height.
You will generally want the ride height set as low as is possible without the car hitting the ground. Your car will hit the ground whenever ride height reaches 0.
FRONT AND REAR RIDE HEIGHT (SMOOTHED)
Displays windows for track position, velocity, front ride height (smoothed) and rear ride height (smoothed). The smoothing process helps to isolate the high frequency movement (eg. bumps) from the low frequency movement (eg. ride height change through heavy braking).
CHASSIS SLIP ANGLE
Displaying windows for track position, longitudinal/lateral G, velocity and yaw. This view is ideal for analysing the chassis direction in relation to that desired.
By studying the slip (yaw) angle you can determine whether you are exploiting all of the available tyre grip. Too high a slip angle will exceed the capability of the tyre, causing the car to loose grip and slide.
Displaying
windows for suspension deflection at each wheel, track position and velocity,
this view is ideal for
analysing how often the car is hitting the bump stops (packers).
TYRE TEMPERATURES (INSIDE/MIDDLE/OUTSIDE)
Displaying windows for crown and camber tyre pressures at each tyre, track position and velocity, this view, FRONT TYRE TEMPERATURES (INSIDE/MIDDLE/OUTSIDE) and REAR TYRE TEMPERATURES (INSIDE/MIDDLE/OUTSIDE), below, is ideal for analysing the distribution of temperature across your tyres.
Tyre crown temperature indicates the temperature at the centre of the tyre minus the average temperature of the inside and outside edges of the tyre.
If the tyre crown temperature is positive this indicates that your tyres are getting hotter in the centre than they are at the edges and vice versa. Try adjusting tyre pressures to balance your centre tyre temperature with that of the edges.
Tyre camber temperature indicates the temperature of the inside of the tyre minus the temperature of the outside of the tyre.
If the tyre camber temperature is positive this indicates that your tyres are getting hotter on the inside than they are on the outside. Try adjusting camber to balance your inside tyre temperature with that of the outside.
Always bear in mind that ideally, you should aim to distribute temperature evenly across the whole tyre.
FRONT TYRE TEMPERATURES (INSIDE/MIDDLE/OUTSIDE)
Displays windows for crown and camber tyre temperature at each front tyre, track position and velocity.
REAR TYRE TEMPERATURES (INSIDE/MIDDLE/OUTSIDE)
Displays windows for crown and camber tyre temperature at each rear tyre, track position and velocity.
TYRE TEMPERATURES (AVERAGED)
Displaying windows for average tyre temperature at each tyre, track position and velocity, this view is ideal for analysing tyre temperature in general
Tyre Temperatures are measured in degrees Centigrade. The optimum temperature (approx.) for each tyre type is as follows:
Hard 114 °C
Soft 112 °C
Intermediate 109 °C
Wet 107 °C
Monsoon 105 °C
Displays windows for tyre wear at each tyre, track position and velocity.
Tyre wear is measured from 1.00 to 0.00, where 1.00 represents a new tyre with zero wear.
Displaying windows for wheel spin at each tyre, track position and velocity, this view is ideal for analysing where you may be locking wheels under braking, or wheel spinning under acceleration.
A positive trace on the wheel spin chart indicates that the wheel is spinning faster than you are travelling (wheel spin) and vice versa.
In order to analyse your telemetry and learn from it you must highlight those areas of the telemetry you wish to compare.
With your view set to Chassis Overview, and some telemetry loaded, move the cursor into the track view window.
Now press and hold down the left mouse button and move the mouse so as to highlight an area of track (such as a difficult corner), finally release the left mouse button.
The track view window now refreshes to display the area of track you have selected. Notice also that the portion of telemetry data corresponding to the area of track you selected is also indicated in the other windows. Also notice that numerical comparison data is displayed for your selection, enabling you to see clearly differences in driver and vehicle performance.
Note: You can actually select areas of your telemetry data in almost any window by holding down the left mouse button and highlighting an area of the telemetry displayed.
With your view still set to Chassis Overview, move the cursor into the velocity window, press and hold down the left mouse button and move the mouse to highlight an area of telemetry.
Notice that the portion of telemetry you have selected in the velocity window is highlighted accordingly in all windows.
Once you have selected a portion of a lap, that selection will stay highlighted when you change to other telemetry views. This allows you to investigate different views to establish what exactly may be causing a problem you see in any particular view.
For example, using the Wheel Spin view, you may see that you are locking wheels under braking in a certain part of track, whilst using the Driver Input view might enable you to see if this problem is caused by down-shifting too early.
By taking time to analyse your telemetry data you should be able to ascertain quite quickly where you may be inconsistent, faster or slower on different laps. As you invest more time you can learn how to improve your vehicle setup too.
Left Mouse Button (held down and drag) - Select a portion of Telemetry Data.
Right Mouse Button - Zoom Out - A step at a time.
Mouse Button 3 - Maximise/minimise selected window.
RETURN - Zoom In to currently selected portion of telemetry.
SPACE - Restore Default Zoom Levels.
BACKSPACE - Unselect Telemetry Data.
